FUSE-HOLDER.

Speclcation of Letters Patent.

BatentedMay '7, 1918.

To all whom it may concern.'

Be it known that we, Osons H. Pmrnn and ALPHONSE F. Pinrna, of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Fuse-Holders; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.o

Our invention relates to fuse holders for electrical circuits, and has for-its purpose to afford a simple structure that can be manufactured at a reasonable cost. A further object of the inventionisfto provide adevice for tliepiirpose mentioned which is strong,Y

durable and ellicient inevery wayyand capable of firml maintaining a fuserin proper relation to t e circuit in whic 'it is disposed- To these and other ends the invention conf sists in certain improvements and combinations of parts, all as will be hereinafter more fully described the novel features being pointedvout in the claims at the end. of the specification.

In the drawings:

Figure 1 is a sectional view of a panel board, showing the application of the invention, with parts appearing in elevation;

Fig. 2 is an end elevation of the device;

Fig. 3 is a longitudinal sectional view on the line 8"-3 of Fig. 2; i

Fig. 4 is a longitudinal tlie line 4*-4 of Fi sectional view on 2, and

Fig. 5 is an ende eration-looking toward the -right of Figui.,

Similar refeigne Icharacters throughout the several views-indicate the same parts.

The present embodiment of the invention includes a conducting member preferably in the form of a metallic sleeve 1 adapted to be inserted in a wall'or' panel 2 and threaded at 3 to receive aprotecting cap 4, while 5 designates an additional threaded portion on the sleeve to which may be attached a, nut 6 having the conductor 7 connected thereto.

8 designates one of a plurality of resilient fuse engaging portions or arms, the inner ends of which are attached to the sleeve 1 in any suitable manner, as by means of rivets 9. Attached to the opposite end of the sleeve 1 is a su port of insulating material preferably in tie form of a sleeve, designated at 10, and secured by the rivets 11. The support 10 also carries a plurality of inwardly within the o provided with a conducting member desig-4 nated general] 12, which has a pair of inwardly exten ing arms 13 attached to the support by means of rivets 14. The support 10 has at its outer end a plurality of longitudinall extending slots or openings 15, and 16 esignates one of a plurality of yieldable fuse enga 'ng members or arms carried by the conducting member 12 and extending enings 15 toward the end of the sleeve 1.' he conducting member 12 also carries an enlargement 17 against which the fuse 18 engages, as shown in Fig. 3. The enlargement 17 is threaded interiorly at 19 to receive a screw 20, by which the conductor 21 is attached and held in place.

The location of a fuse when operatively positioned is' shown in Fig. 3. In order to position .the fuse it is inserted between the arms 8, and force inwardly until it engages the arms 16 and the enlargement 17. The yieldable engaging members serve to hold the fuse in rigid relation, and at the same time. to maintain an unbrokencircuit. The

structure is inexpensive to manufacture and possesses considerable advantage accruing from the strength and durability of the device and the ease with which a fuse can be inserted or removed. It also possees considerable utility in its applicability to panel boards in various types 'of electrical equipment, such as for instance are em loyed 'in the control of dental apparatus w ere it is desirable to 'conceal the parts and at the same time fuse.

We claim asour invention:

L A fuse holder comprisin a conducting member, a plurality of yie dable engaging portions attached at one end thereof, a support of insulating material attached' at the opposite end of said conductin member, and a luralityof yieldable l se engaging mein ers secured to the support.

permit ready accessibility to a 2. A fuse holder comprisin a conducting portions attached at one end thereof, a, supporting sleeve of insulating material attached at the o posite end of the conducting sleeve, and a p urality of yieldable fuse engaging members secured to the supporting sleeve.

4. A fuse holder comprisin sleeve, a. plurality of yieldabe fuse engaging portions attached to and extending beyond one end of the conducting sleeve, a support of insulating material attached to the conducting sleeve and projecting beyond the vopposite end thereof, and a plurality of yieldable fuse engaging members secured to the support and projecting inwardly therefrom toward the'conducting sleeve.

5. A fuseholderzomprism a'conducting member, a pluralit of yiclda Ie fuse engaging portions attaclied to and extending be# yond oneend ofthe, conducting member, a support of insula'tin material attached to the conducting mem er and projecting bea conducting yond the opposite 'end thereof and having a series. of 'slots or openings extending 1ongitudinally from its Aouter-engl, and a lurality of fuse lengagingmembers secured to the support an located in said slots.

6. A -fuse holder comprising a conducting member, a plurality of .yiel

able fuse engaging portions attached to and extending beyond one end thereor, a support of insu ating material attached to the conducting member and projecting beyond the opposite end thereof having a series of slots or openings extending longitudinally from its outer end, and a second conducting member arranged within the support and carrying a. plurality of fingers ocated in said slots or openings and extendin from the end of the support, silient fuse. engaging members.

7. A fuse holder comprising a conducting member threaded exteriorly at one end to receive a cap, a pluralityfof yieldable fuse engaging portions attached to the conducting member and extending beyond said end thereof, a support'of insu ating material attached at the op site end of said conducting member, aus a. vplurality of yieldable orming re- 'fuse engaging members secured to the support.'
